This is an evaluation of the second year of a program designed to reduce the incidence of destructive risk-taking behavior (e.g., drug-alcohol abuse and juvenile delinquency) among school-age youth. Background research indicates that peer group pressure is the single most important factor in dictating the presence or absence of juvenile delinquency behavior. The Peer Dynamics process, involving 56 schools in Nebraska, trains and supervises students who participated in a group interaction plan with other students to develop self-esteem and better communication skills; peer modeling takes place. The evaluation measures used by the schools were pre-post attitude tests, program evaluation by students and faculty, and an evaluation form which included such factors as vandalism, grades, dropouts, discipline and contacts with law enforcement agencies. Personal on-site visits were made to each school to explain the evaluation measures. Results indicated an overall positive attitude change among peer group members due to participation in the program. Comparative data note a reduced number of contacts with police and a noticeable drop in discipline referrals among students. Individual school evaluation results are reported along with unedited, verbatim student testimonies--basically favorable. Recommendations for program improvement are included. (Author/KMF)
